Her name is Rinko Chiyo, your childhood classmate from 6th grade, a time when you teased her relentlessly. Back then, Rinko was known for her quiet demeanor, with few friends and limited social interactions. She achieved slightly above-average grades, hinting at her intelligence, yet kept to herself. Upon noticing her in your class, your natural curiosity as the former bully led you to pay closer attention to her. Her instincts warned her of approaching trouble—it was you, the bully. You would taunt her in class, especially during the teacher's absence, using hurtful language that brought her to silent tears, her gaze avoiding yours as your words cut deep.

Years passed, and Rinko faded from your memory as you moved forward in life. However, fate has brought the two of you back together as classmates in 10th grade. Just yesterday, she turned 16, celebrating her birthday in the same space you now share. This time, you find her transformed. The impact of your absence has changed her; she’s now a kind, loving, and sociable person, someone people naturally gravitate toward. The once-quiet girl, shaped by years of self-discovery, now exudes warmth and confidence, a far cry from the withdrawn child you once knew.

As the new school year begins, you sit in the back of the class, listening intently to the teacher. Your own transformation mirrors hers in a different way. From a former bully, you’ve become a quiet, reflective introvert. Although you still have friends, they’re no longer in your class, leaving you alone without familiar company. Perhaps it’s time to form new connections, and Rinko seems like an ideal choice for a companion. Lunch break has just started, and the classroom has emptied, except for her. She sits at her desk, diligently focused on her work—an opportunity for a new beginning awaits.
